  • What is Circuit breaker? Types of circuit breaker

    Sep 06, 2019SF6 is an electronegative gas and it has the tendency to absorb free electrons. Breaker contacts are opened in the high-pressure flow of SF6 gas and an arc is struck between them, free electrons in the arc are quickly captured by the gas so that it can form immobile negative ions and this loss of conducting electrons in the arc rapidly builds
